GENERAL DESCRIPTION
The AD584 is an eight-terminal precision voltage reference offering pin-programmable selection of four popular output voltages:
10.000 V, 7.500 V, 5.000 V and 2.500 V. Other output voltages,
above, below or between the four standard outputs, are available
by the addition of external resistors. Input voltage may vary between
4.5 V and 30 V.
Laser Wafer Trimming (LWT) is used to adjust the pinprogrammable output levels and temperature coefficients,
resulting in the most flexible high precision voltage reference
available in monolithic form.
In addition to the programmable output voltages, the AD584 offers
a unique strobe terminal which permits the device to be turned
on or off. When the AD584 is used as a power supply reference,
the supply can be switched off with a single, low-power signal.
In the “off” state the current drain by the AD584 is reduced to
about 100 µA. In the “on” state the total supply current is typi-
cally 750 µA including the output buffer amplifier.
The AD584 is recommended for use as a reference for 8-, 10-,
or 12-bit D/A converters which require an external precision
reference. The device is also ideal for all types of A/D converters of up to 14-bit accuracy, either successive approximation or
integrating designs, and in general can offer better performance
than that provided by standard self-contained references.
The AD584J, K, and L are specified for operation from 0°C to
70°C; the AD584S and T are specified for the –55°C to +125°C
range. All grades are packaged in a hermetically sealed eightterminal TO-99 metal can; the AD584 J and K are also available
in an 8-lead plastic DIP.

PRODUCT HIGHLIGHTS
1. The flexibility of the AD584 eliminates the need to design-in
and inventory several different voltage references. Further
more one AD584 can serve as several references simultaneously
when buffered properly.
2. Laser trimming of both initial accuracy and temperature coefficient results in very low errors over temperature without the
use of external components. The AD584LH has a maximum
deviation from 10.000 V of ±7.25 mV from 0°C to 70°C.
3. The AD584 can be operated in a two-terminal “Zener” mode
at 5 V output and above. By connecting the input and the
output, the AD584 can be used in this “Zener” configuration
as a negative reference.
4. The output of the AD584 is configured to sink or source
currents. This means that small reverse currents can be tolerated in circuits using the AD584 without damage to the reference and without disturbing the output voltage (10 V, 7.5 V,
and 5 V outputs).
5. The AD584 is available in versions compliant with MIL-STD-
883. Refer to the Analog Devices Military Products Databook
or current AD584/883B data sheet for detailed specifications.

CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily
accumulate on the human body and test equipment and can discharge without detection. Although
the AD584 features proprietary ESD protection circuitry, permanent damage may occur on devices
subjected to high-energy electrostatic discharges. Therefore, proper ESD precautions are
recommended to avoid performance degradation or loss of functionality.
